Author, editor, and science fiction archivist Philip Harbottle recently published his 80th video on British Science Fiction, this time exploring the latest release of a single book: John Russell Fearn’s ‘Vargo Statten’ novel, The Catalyst, recently reprinted for the tenth time in Italy by Luigi Cozzi’s Profondo Rosso imprint as “L’oro viene dal cielo”.
Cozzi has produced new, accurate translations from the original English editions, and Phil contributed an afterword to this latest release.

The Catalyst, first published by Scion in 1951, is classic science fiction: explorers bring a mysterious rock from Mercury to Earth, only for it to be stolen, along with Mercury diamonds. The rock’s catalytic reaction with water leads to deadly consequences, including people being turned into gold, echoing the King Midas myth.
Fearn’s premise is rooted in chemistry: Mercury, a waterless world, produces a catalyst that reacts explosively with moisture. In the story, a thief’s perspiration triggers the transformation, turning water – and people – into gold.
“Large diamond fields on the surface of Mercury, along with the catalyst rock, form a central part of the plot of The Catalyst,” Phil notes. “When I first read this novel in the 1950s, I thought the idea of lots of diamonds on Mercury was just a flight of fancy. But astonishingly, modern day scientists are now speculating that Mercury’s surface may well be studded with diamonds.
“They believe that meteorites may have turned much of the planet’s graphite crust into precious gemstones: diamonds may actually litter the surface of the planet. Those diamonds could have been forged by space rocks pummelling Mercury for billions of years. The planet’s long history of being pelted by meteorites, comets and asteroids is clear from its cratered crust. Now, computer models suggest that these impacts may have had another effect: meteorite strikes may have baked about one third of Mercury’s crust into diamonds!”
The ongoing Bepi Colombo space mission – a joint European Space Agency and Japan Aerospace Exploration Agency mission to Mercury – may soon shed light on these theories. It reaches the solar system’s innermost planet in November 2026.



The Catalyst’s core idea evolved from Fearn’s earlier pulp story, “The Man Who Bought Mars,” where a villain is turned to gold by touching a stalagmite. The novel has been widely translated and adapted, including French, Italian, Brazilian, and graphic novel editions, and was even featured on Italy’s most popular TV quiz show, Lascia o Raddoppia.

Plus, you may have missed his previous release: a tour of the bookshops of Hay-on-Wye, searching for classic science fiction. It proved a fun day out, which, after a few disappointments, and a lack of SF in some shops, eventually turned up some gems…



John Francis Russell Fearn was born in Worsley, near Manchester, on 5th June, 1908. As a child he devoured imaginative fiction, beginning to write SF at the age of ten – in imitation of Wells and Verne – on a typewriter he was given for his birthday. Extremely prolific, Fearn used many pseudonyms. During the 1930s he wrote for magazines, including the US Pulp magazines, but during World War Two he switched to books, becoming a central figure in the post-war paperback boom. He wrote numerous westerns, crime stories and romances as well as SF, most of which appeared under the names Vargo Statten and Volsted Gridban (the latter pseudonym being taken over from E. C. Tubb).
Altogether, Fearn published 18 stories in the pre-war Astounding, and went on to write more than 100 other stories in all the leading American pulp magazines through to 1948.
The Encyclopedia of Science Fiction notes that “his best work is vigorous and occasionally vivid’ and the influential British SF agent and editor, John Carnell, paid this tribute: “Fearn was one of the Greats of the earlier ages, and his name should be there with Hugo Gernsback, John W. Campbell, Stanley G. Weinbaum, Murray Leinster, and all the others whose thoughts and works formulated today’s modern science fiction.”
Philip Harbottle: Author and Archivist Extraordinaire

Philip Harbottle is a life-long science fiction fan, regarded as a world authority on the works of John Russell Fearn, whose credits encompass writing “Garth” for the Daily Mirror, and the “Golden Amazon” for Spaceship Away (adapting Fearn’s stories).
He’s also very kindly contributed a number of synopses of early “Garth” stories to downthetubes, which we are adding as time permits.
Back in the 1950s, he adapted some of the Radio Luxembourg Dan Dare radio shows into comics at a young age – the only record of some of these tales known to exist, since very few recordings survive.
